BLEXBot — WebMeUp backlink crawler
BLEXBot is a crawler associated with WebMeUp/SEO backlink tooling. It is a third-party crawler that builds a backlink index, not a search engine, so it does not affect search rankings directly. Its robots.txt token is BLEXBot; some specifics are marked partially verified.
What this means
BLEXBot crawls the web to build a backlink index associated with WebMeUp's SEO tooling. Like other third-party SEO crawlers, it is not a search engine: its visits do not directly change your Google or Bing rankings.
Seeing BLEXBot in logs means your site is being included in that backlink dataset. Some specifics about its current operation are not as fully documented as for major crawlers, so this entry is marked partially verified.
robots.txt considerations
BLEXBot is described as honouring robots.txt and providing a self-identifying URL in its user agent. To slow or exclude it, target the BLEXBot token. The user agent is spoofable, so verify against its published guidance where authenticity matters, and do not invent IP ranges.

How it appears in analytics and logs
A request carrying the BLEXBot token is a third-party backlink crawler fetching a URL — a bot event from an SEO/backlink tool, not a search engine and not a human visit. It does not influence search rankings by itself.
Diagnostic use case
Recognise BLEXBot as third-party backlink crawling, decide whether to allow it, and control it via robots.txt using its token.
What WebmasterID can help detect
WebmasterID classifies BLEXBot server-side as an SEO crawler and shows it separately from human traffic and search-engine crawlers, so third-party backlink crawling is visible without log parsing.
Common mistakes
- Assuming BLEXBot crawling affects search rankings — it does not.
- Treating backlink-tool crawl hits as human visits.
- Asserting documented behaviour where coverage is partial.
Privacy and accuracy notes
Identification uses only the user agent — no human identity. WebmasterID records BLEXBot as a bot event, separate from human analytics.

AhrefsBot is the crawler operated by Ahrefs to build its SEO and backlink index. It is a third-party crawler, not a search engine, so it does not affect Google or Bing rankings directly. It uses the AhrefsBot robots.txt token and is documented as respecting robots.txt and crawl-delay.
- Managing third-party SEO crawler load
Third-party SEO crawlers such as AhrefsBot and SemrushBot can generate significant request volume without contributing to search visibility. You can manage their load by targeting their tokens in robots.txt, using crawl-delay where the crawler supports it, and blocking those that bring no value to you.
